Title: Oil tank construction for super tankers - uses ring-shaped transverse webs to support centre tanks
IPC: B63B25/10
Filed: 1973-12-28
Abstract: On the circumference of a centre tank (3), there are arranged a deck transverse web (5) and a bottom transverse web (7), as arranged in the conventional structure, and there are newly arranged centre tank transverse webs (10) on both boards.

Title: Connection for flexible tubes - has retaining ring for radially compressible and sealing rings
IPC: F16L19/08
Filed: 1973-12-21
Abstract: The compression-type connector can be fitted directly over the tab end without any previous unscrewing or disassembly of components.

Title: Solid state D.C. to D.C. converter - includes transformer with rectifier and feedback
IPC: H02M3/28
Filed: 1974-08-19
Abstract: The stabilised solid state circuit converting D.C. to D.C. produces a voltage output normally of a different magnitude to that of the supply and is intended for a wide range of applications, e.g. vehicle ignition circuits, domestic record player amplifiers.
